摘要

The syntheses and reactions of 4H-1, 3, 4-benzothiadiazines have been of recent interest to a number of research groups, including our own. We have used two general approaches to syntheses, one based on hydrazonoyl halides and the other on N'-arylbenzothiohydrazides. In each case the"-aryl group becomes incorporated in the benzothiadiazine ring system, and the synthesis leads to 2-aryl-4-acyl-and 2, 4-diary1-4H-1, 3, 4-benzothiadiazines.'
